MEANS FOR PACKING REFRIGERATOR-DOORS.

Specification of Letters Patent. Application filed November 24, 1913.

Patented May 12, 1914. Serial No. scasae.

To all whom it may concern:

Be it known that I, CALVIN B. PATCH, a citizen of the United States, residing at. Glenellyn, in the county of Dupage and State of Illinois, have invented a certain new and useful Improvement in Means for Packing Refrigerator-Doors, of which the following is a full, clear, concise, and exact debeing had to the accompanying drawings, forming a part of this specification.

My invention relates to means for packing refrigerator doorsmore particularly the doors of refrigerator cars.

The object of my invention is to .provide a cheap, simple and efficient device for packing refrigerator doors.

In the drawings forming a part of this specificationFigure 1 is a cross sectional view of a pair of refrigerator doorsshowing sections of the adjacent door posts; Fig. 2 is an enlarged elevation of a portion of the packing mechanism in position; Fig. 3 is a cross sectional view on line 3-3 of Fig. 2 showing the position of the parts of the clevice, and not under compression; Fig. 4 is a cross sectional View showing the position of the parts of the packing mechanism when fully compressed.

Referring to the drawings 5, 5 represent doors, which may be suitably hinged to the door posts 6, 6. My device is adapted to be used between the doors and the parts of the doorframe meeting therewith, which for convenience I call the surrounding wall of the door-frame. It is also adapted to be used between the meeting edges of the doors.

The numeral 7 indicates a groove, preferably placed in the surrounding wall of the door-frame, though it will be apparent from the description hereinafter following that the same may be placed in the outer edges of the door. The numeral 8 indicates a similar groove in one of the doors at their meeting edges. The packing device hereinafter described is adapted to be placed in these grooves, and comprises a backing strip 9, a pair of actuating strips 9*, 9 therefor, springs 10, 10 for said actuating strips, and packing 11. The packing 11 preferably consists of a flexible packing material 12 and a facing strip 13, preferably of canvas covering the same. The said packing material and facing strip are secured at either side of the groove by suitable means, preferably the nails 14, 14.

The backing strip 9 comprises a preferably wooden strip having an outer face 15 engaging against the packing material, the said strip having beveled rear corners, as indicated at the numerals 16, 16, which are adapted to slidingly engage the beveled forward faces 17 of the actuating strips 9 The rear face 18 of each of said actuating strips is adapted to slidingly engage the bottom face 19' of the groove 7. Between the outer face 20 of each actuating strip and the adjacent side wall 21 of the groove 7 is arranged at suitable intervals a series of springs 10, which may be of any suitable kind, but preferably each spring is substantially U-shaped, and secured preferably by the brads 22 to the outer face 20 of the actu- I ating strip 9 the free ends of said spring engaging against the adjacent wall 21 of the groove 7.

In its expanded position, as illustrated in Fig. 3 of the drawings, the outer face 15 of the backing strip projects beyond the edges of the groove 7 the backing strip being kept tight against the packing by the actuating 7 strips, which are forced transversely of the groove 7 toward each other by the pressure of the springs 10. Upon the closing of a door against the packing the backing strip 9 is forced inwardly, the beveled edges 16 thereof sliding against the beveled faces 17 of the actuating strips 9, the said actuating strips being kept thereby in tight engagement against the bottom face 19 of the groove 7 and also thereby being spread outwardly, and in such movement being resisted by the springs 10.

It will be observed that in this construc tion not only is a tight compression of the backing strip against the packing insured, but the passage of air through the packing at either side of the backing strip and back of the same is prevented by the actuating strip 9*.

I claim V 1. In a packing for refrigerator doors, the combination with a door and the surrounding wall of the door-frame, of a groove in one of the meeting edges of the same, a flexible material bridging said groove, a backing strip engaging said flexible material, actuating strips and springs, the actuating strips engaging the backing strip and moving transversely to the direction of movement of the backing strip, said actuating strips being engaged by the springs.

2. In a packing for refrigerator doors, the combination with a door and the surrounding wall of the door-frame, of a groove in one of the meeting edges of the same, a flexible material bridging said groove, a backing strip engaging said flexible material, actuating strips and springs, the actuating strips being in sliding engagement with the backing strip and with the bottom of said groove, the springs being seated between the sides of said groove and the actuating strips.

3. In a packing for refrigerator doors, the combination with a door and the surrounding wall of the door-frame, of a groove in one of the meeting edges of the same, a flexible material bridging said groove, a backing strip engaging said flexible material, actuating strips and springs, the rear edges of said backing strips beingdonble, the actuating strips having beveled faces slidably engaging the beveled faces of the backing strip, the springs being seated between the actuating strips and the sides of the groove. 7

4. In a packing for refrigerator doors, the

combination with a' door and the surrounding wall of the door-frame, of a groove in one of the meeting edges of the same, a

flexible material bridging said groove, a backing strip engaging said flexible material, actuating strips and springs, the rear edges of the backing strips being beveled, the adjacent faces of the actuating strips bein beveled and slidably engaging the backing strip, the rear faces of the actuating strips being in sliding engagement with the bottom of the groove, and the springs being seated between the edges of the groove and said actuating strips. v

5. In a packing for refrigerator doors, the combination with a door and the surrounding wall of the door-frame, of a groovein one of the meeting edges of thesame, a flexi ble material bridging saidv g1foove,,a backing strip engaging said flexible material, actuating strips and springs, the rear edges of said backing strip being beveled and the adjacent faces of the actuating strips slidably engaging therewith, the springs being adapted to resist the spreading movement of the actuating strips.
